From e44674dfaee27bc449e0f3de65a0925851a598a3 Mon Sep 17 00:00:00 2001 From: Matheus Alcantara Date: Thu, 9 Apr 2026 14:09:05 -0300 Subject: [PATCH v1 1/2] docs: Include database collation check on SQL from ALTER COLLATION Previously the alter_collation.sgml documentation section include a SQL that can be used to identity all collations in the current database that need to be refreshed due to a collation version miss match and the objects that depend on them. However if there is objects that use the database collation these objects are not returned by the query. This commit improve the query on alter_collation.sgml to include the database collation version check too to report such cases. --- doc/src/sgml/ref/alter_collation.sgml | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/doc/src/sgml/ref/alter_collation.sgml b/doc/src/sgml/ref/alter_collation.sgml index a40a31442a8..f0c3af20b95 100644 --- a/doc/src/sgml/ref/alter_collation.sgml +++ b/doc/src/sgml/ref/alter_collation.sgml @@ -164,7 +164,13 @@ SELECT pg_describe_object(refclassid, refobjid, refobjsubid) AS "Collation", pg_describe_object(classid, objid, objsubid) AS "Object" FROM pg_depend d JOIN pg_collation c ON refclassid = 'pg_collation'::regclass AND refobjid = c.oid - WHERE c.collversion <> pg_collation_actual_version(c.oid) + JOIN pg_database db ON db.datname = current_database() + WHERE c.collprovider IN ('d', 'c') + AND ( + (c.collprovider = 'd' AND db.datcollversion <> pg_database_collation_actual_version(db.oid)) + OR + (c.collprovider = 'c' AND c.collversion <> pg_collation_actual_version(c.oid)) + ) ORDER BY 1, 2; ]]> -- 2.53.0
